Background: Breast cancer, a type of malignant tumor, affects women more than men. About one third of women with breast cancer die of this disease. Hence, it is imperative to find a tool for the proper identification and early treatment of breast cancer. Unlike the conventional data mining algorithms, fuzzy logic based approaches help in the mining of association rules from quantitative transactions.Methods: In this study a novel fuzzy methodology IFFP (Improved Fuzzy Frequent Pattern Mining), based on a fuzzy association rule mining for biological knowledge extraction, is introduced to analyze the dataset in order to find the core factors that cause breast cancer. This method consists of two phases. During the first phase, fuzzy frequent itemsets are mined using the proposed algorithm IFFP. Fuzzy association rules are formed during the second phase, indicating whether a person belongs to benign or malignant. This algorithm is applied on WBCD (Wisconsin Breast Cancer Database) to detect the presence of breast cancer.Results: It is determined that the factor, Mitoses has low range of values on both malignant and benign and hence it does not contribute to the detection of breast cancer. On the other hand, the high range of Bare Nuclei shows more chances for the presence of breast cancer.Conclusion: Experimental evaluations on real datasets show that our proposed method outperforms recently proposed state-of-the-art algorithms in terms of runtime and memory usage.  相似文献

Breast cancer is one of the most prevalent types of cancers in females, which has become rampant all over the world in recent years. The survival rate of breast cancer patients degrades considerably for patients diagnosed at an advanced stage compared to those diagnosed at an early stage. The objective of this study is two folds. The first one is to find the most relevant biomarkers of breast cancer, which can be attained from regular blood analysis and anthropometric measurements. The other one is to improve the performance of current computer-aided diagnosis (CAD) system of early breast cancer detection. This study utilized a recent data set containing nine anthropometric and clinical attributes. In our methodology, first, we performed multicollinearity analysis and ranked the features based on the weighted average score obtained from four filter-based feature evaluation methods such as F-score, information gain, chi-square statistic, and Minimum Redundancy Maximum Relevance. Next, to improve the separability of the target classes, we scaled and weighted the dataset using min-max normalization and similarity-based attribute weighting by the k-means clustering algorithm, respectively. Finally, we trained standard machine learning (ML) models and evaluated the performance metrics by 10-fold cross-validation method. Our support vector machine (SVM) model with radial basis function (RBF) kernel appeared to be the most successful classifier by utilizing six features, namely, Body Mass Index (BMI), Age, Glucose, MCP-1, Resistin, and Insulin. The obtained classification accuracy, sensitivity, and specificity are 93.9% (95% CI: 93.2–94.6%), 95.1% (95% CI: 94.4–95.8%), and 94.0% (95% CI: 93.3–94.7%), respectively; these performance metrics outperformed state-of-the-art methods reported in the literature. The developed model could potentially assist the medical experts for the early diagnosis of breast cancer by employing a set of attributes that can be easily obtained from regular blood analysis and anthropometric measurements.  相似文献

BackgroundThe prediction of breast cancer subtypes plays a key role in the diagnosis and prognosis of breast cancer. In recent years, deep learning (DL) has shown good performance in the intelligent prediction of breast cancer subtypes. However, most of the traditional DL models use single modality data, which can just extract a few features, so it cannot establish a stable relationship between patient characteristics and breast cancer subtypes.DatasetWe used the TCGA-BRCA dataset as a sample set for molecular subtype prediction of breast cancer. It is a public dataset that can be obtained through the following link: https://portal.gdc.cancer.gov/projects/TCGA-BRCAMethodsIn this paper, a Hybrid DL model based on the multimodal data is proposed. We combine the patient's gene modality data with image modality data to construct a multimodal fusion framework. According to the different forms and states, we set up feature extraction networks respectively, and then we fuse the output of the two feature networks based on the idea of weighted linear aggregation. Finally, the fused features are used to predict breast cancer subtypes. In particular, we use the principal component analysis to reduce the dimensionality of high-dimensional data of gene modality and filter the data of image modality. Besides, we also improve the traditional feature extraction network to make it show better performance.ResultsThe results show that compared with the traditional DL model, the Hybrid DL model proposed in this paper is more accurate and efficient in predicting breast cancer subtypes. Our model achieved a prediction accuracy of 88.07% in 10 times of 10-fold cross-validation. We did a separate AUC test for each subtype, and the average AUC value obtained was 0.9427. In terms of subtype prediction accuracy, our model is about 7.45% higher than the previous average.  相似文献

Background

Chronic kidney disease (CKD) is a disorder associated with breakdown of kidney structure and function. CKD can be diagnosed in its early stage only by experienced nephrologists and urologists (medical experts) using the disease history, symptoms and laboratory tests. There are few studies related to the automatic diagnosis of CKD in the literature. However, these methods are not adequate to help the medical experts.

Methods

In this study, a new method was proposed to automatically diagnose the chronic kidney disease in its early stage. The method aims to help the medical diagnosis utilizing the results of urine test, blood test and disease history. Classification algorithms were used as the data mining methods. In the method section of the study, analysis data were first subjected to pre-processing. In the first phase of the method section of the study, pre-processing was applied to CKD data. K-Means clustering method was used as the pre-processing method. Then, the classification methods (KNN, SVM, and Naïve Bayes) were applied to pre-processed data to diagnose the CKD.

Results

Highest success rate obtained by classification methods is 97.8% (98.2% for ages 35 and older). This result showed that the data mining methods are useful for automatic diagnosis of CKD in its early stage.

Conclusion

A new automatic early stage CKD diagnosis method was proposed to help the medical doctors. Attributes that would provide the highest diagnosis success rate were the use of specific gravity, albumin, sugar and red blood cells together. Also, the relation between the success rate of automatic diagnosis method and age was identified.  相似文献

Down syndrome critical region 1 gene (DSCR1) is an anti-angiogenesis gene that inhibits the growth of tumor cells. In this study, the role of autophagy and apoptosis in DSCR1-induced cytotoxicity were investigated in MDA-MB-468 breast cancer cells. Lentivirus vector harboring DSCR1 (LV-DSCR1+) was constructed in HEK 293 cells and the optimal dosage of lentivirus vector for infection was determined by the MTT assay. After infection of cells using LV-DSCR1+, acridine orange and ethidium bromide staining was performed to investigation of apoptosis and autophagy. Expression of DSCR1 and marker genes for angiogenesis (VEGF), apoptosis (Bax and Bcl2) and autophagy (LC3 and Beclin) were determined by Real time PCR. The cellular morphological changes related to apoptosis and autophagy was happened after 48 hours of viral infection. Fragmented bright orange nucleuses and vacuoles were observed due to the cell apoptosis and autophagy after acridine orange and ethidium bromide staining. Upregulation of Bax, Lc3, DSCR1 and Beclin1 and downregulation of Bcl2 and VEGF was detected due to treatment with LV-DSCR1+. These results demonstrated that LV-DSCR1+ can induce apoptosis and autophagy, therefore suggesting that it may serves as an efficient tool to breast cancer treatment.  相似文献

紫杉醇虽被证明在多种肿瘤治疗中均具有良好的效果,但其有一个严重的缺陷:水溶性低。临床使用中需使用聚氧乙烯蓖麻油(CremphorEL)或无水乙醇作为溶剂,但其在体内降解时能释放组胺,导致严重的过敏反应以及肾毒性和神经毒性等不良反应,此外还存在患者耐受性差、血药浓度低、靶向性差等不足。在乳腺癌的诊断和治疗中,纳米技术改变了紫杉醇制剂的特征参数而使药物表现出缓释、控释性及靶向性等优势,解决了传统紫杉醇制剂水溶性差的缺点,提高了药物的生物利用度,并明显降低了紫杉醇的毒性和副作用,给紫杉醇药物在体内运输提供了新途径。  相似文献
